What is the source of these figures? In my experience many CF level upgrades did not require a structure increment and others had specific requirements. E.g. add nn MBs i.s.o. increment by nn %. 75% is a guess and in my opinion too much.
We are at level 21 now. If my docs are reliable, the last increase required by CF level was at level 15. So if level 22 does not require a structure increase, level 17 structures are probably OK.
